SLED-BRAKE.

Specification of Letters Patent.

Patented Dec. 10, 1907.

Application filed March 3. 1906. Serial No. 304.048.

To all whom it may concern:

Be it known that I, GUDMUNDER S. Gun MUNDSON, a subject of the King of England, residing at Ardal, in the Province of Manitoba, Dominion ofCanada, have invented certain new and useful Improvements in Sled-Brakes; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

This invention relates to brakes for bob sleds and has for its object to provide a brake of this character which shall be positive in action and readily operable.

A further object of the invention is to pro vide a brake which may be used to slacken the speed of the sled or to entirely stop the same as desired.

lVith these and other objects in view, the invention consists in the construction and arrangement of parts shown in the accompanying drawings, in which Figure 1 is a side elevation of a portion of a bob sled showing my invention applied thereto. Fig. 2 is a vertical section through a part .of the runner. Fig. 3 is an elevation of the brake detached. Fig. 4 is a section on the line 44 of Fig. 1.

Referring to the drawings, 6 denotes the runners of a bob sled to the upper face of each of which is secured, by means of bolts 7, a segmental rack 8. To each of the segmental racks 8 is pivoted,'as at 9, a lever 10 provided with the usual latch-rod 11, grip 12 and pawl 13 which latter is adapted for engagement between any pair of a series of teeth 14. Pivoted to each of the levers 10 above their pivots 9 is a pair of brake-rods 15 and 16 which are each provided with a pointed lower end 17. The brake-rods 15 and 16 but should it be desired to bring the sled to a full stop, the lever is rocked forwardly thereby forcing the brake-rod 15 into the snow or ground in a positive manner. If when ascending a hill, it is desired to stop, the lever is rocked backwardly forcing the brake-rod 16 into the road or the snow and it will be seen that any tendency of the sled toward backward movement will result in more firmly embedding the brake-rod in the road.

From the foregoing, it will be seen that I have provided a brake for sleds which will be efficient in action and simple in construction.

What is claimed is A device of the class described, the combination with a runner provided with a pair of downwardly diverging bores, of a lever mounted for pivotal movement thereon, a pair of brake rods pivotally connected with said lever and extending one through the forward bore and the other through the rear bore and at an angle to each other, the lever being adapted to be rocked to bring the rear brake rod into frictional engagement with the surface over which the runner is traveling and being also adapted to be rocked to bring the forward brake rod into positive engagement with the surface over which the runner is traveling.

- In testimony whereof, I affix my signature, in presence of two witnesses.
